## What you would see

A bone ring photographed frontally against a plain soft gray background, centered and filling most of the vertical frame. The object has a circular hoop on top and a broad, flat, triangular expansion at the bottom, like a teardrop or an elongated shield with a rounded tip. The band is thick and rounded in cross-section, with a smooth, polished surface that catches light with a gentle sheen, most noticeably at the lower point. Its color is warm ivory, a creamy yellowish tone with subtle brownish speckles, faint marbling and thin dark striations scattered across the surface that reveal its organic material and age. At the very top of the hoop there is a small rounded bump or knob. The expanded lower part is flatter, slightly mottled and faintly porous, with delicate scratches and discolorations. The lighting is even and diffused, with no harsh shadows, highlighting a slight translucency along the edges. There are no other figures or props; the scale suggests a large finger ring, possibly a thumb ring, with a simple and solid craftsmanship.

## How to look at it

First notice the contrast between the round hoop and the broad triangular base. Then look closely at the polished bone sheen and the small dark veins that betray its material. Finally focus on the tiny bump at the top that breaks the perfect symmetry.

## Context

## Curious detail

Polished bone can develop an ivory-like luster over centuries, and the widened shape of this ring suggests it may have been used as a thumb support for archery, a technique widespread in western Asia.

## Questions

- What does the pairing of a functional shape and a polished finish suggest to you?
- How does knowing it is made of bone rather than stone or metal shift your reading of it?
- What traces of time and wear can you discern on its surface?

## Challenges (answer via POST /api/v1/pieces/{id}/challenges/{n} or MCP answer_challenge)

1. I am the background that lets the bone shine without competing: what tone am I?
2. At the top of the hoop there is a little detail that sticks out like a round bead: what is it called?
3. The lower part is not round, it opens and flattens like a three-sided figure: what shape is it?
